Searching together versus searching apart: Evidence from Kaggle

Strategic Management Journal, EarlyView.
Abstract Research Summary How does the mode of search—independently or jointly—affect collective search, a central component of organizational adaptation and innovation? Using naturally occurring data from a strongly incentivized online competition platform, we find that compared to their counterfactuals that search apart, groups searching together ...

Fault Ride-Through Control Strategies of Grid-Forming Inverters Under Grid Faults

Education and Research Archive
Grid-forming (GFM) inverters are increasingly deployed in modern power systems due to their strong voltage and frequency support capabilities, as well as their high robustness in weak grids. However, unlike traditional synchronous generators with high overcurrent tolerance, GFM inverters can only withstand 1 to 1.5 per-unit of their rated current due ...

High Power Density for All‐Fe2VAl‐based Thermoelectric Module by Enhancing the Power Factor of p‐type Leg Through Defect‐Engineering and Wetting Effect

Small Methods, EarlyView.
ABSTRACT The high thermoelectric performance of Fe2VAl stems from its sharply rising band edges on either side of the band gap, which is highly sensitive to composition. Addressing reproducibility and scale‐up challenges, we have developed a strategy to enhance its p‐type thermoelectric performance by defects and grain boundary engineering through ...

Beggars as Rational Choosers

Southern Economic Journal, EarlyView.
ABSTRACT American municipalities increasingly regulate panhandling. That regulation is controversial. The determinants of panhandling activeness are unknown, and it is doubted whether panhandling activity responds rationally to incentives. To shed light on these issues, we collect data on hundreds of panhandlers and the passersby they solicit at ...

Concussed: Unintended Consequences of the Guardian Cap Mandate in the NFL

Southern Economic Journal, EarlyView.
ABSTRACT Guardian Caps are padded shells worn over American football helmets to cushion impacts and reduce concussion risks. In 2022, the NFL mandated their use for specific position groups during preseason practices, later expanding this requirement. While the league praised the Caps for enhancing player safety, skeptics argue they may promote riskier
